Userspace `ipset` command forbids family option for hash:mac type: ipset create test hash:mac family inet4 ipset v6.30: Unknown argument: `family' However, this check is not done in kernel itself. When someone use external netlink applications (pyroute2 python library for example), one can create hash:mac with invalid family and inconsistant results from userspace (`ipset` command cannot read set content anymore). This patch enforce the logic in kernel, and forbids insertion of hash:mac with a family set. Since IP_SET_PROTO_UNDEF is defined only for hash:mac, this patch has no impact on other hash:* sets Signed-off-by: Florent Fourcot <florent.fourcot@wifirst.fr> Signed-off-by: Victorien Molle <victorien.molle@wifirst.fr> Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
